Undersea Walk An activity suitable for all! Indeed, even non-swimmers can definitely enjoy this experience underwater. You are taken on a short boat ride offshore; as you begin to descend to the sea bed using a ladder, you are equipped with a helmet that will enable you to breathe normally, and you're ready to enjoy your underwater stroll at a depth of 2.5 - 3 metres. The helmet keeps your head completely dry, so you can even wear glasses or contacts. Our guides are there all along to make sure that you have fun in perfect safety.
